Well, the thing is I'm new to this whole webstart business, and so I followed the tutorial by Kevin Glass which states:

So I'm assuming then that it need not be signed?

Mine isn't. It runs. You should only need to sign it if you're doing something which requires you to step outside the sandbox - e.g. accessing the network or the filesystem. There's very little need to do that in a 4k Java game.

Ok now after reading instructions. It don't worked as i understood it. Maybe it's just as english is not my natural language So just as a hint for the instructions, as i now seem to understood the rules:You should make it more obvious that all alienz with the correct row/column-amount are removed.

Fun mechanic, but the 2-second timer on the combo bonus really penalises laptop players using a trackpad.

I think it's MEANT to be 5 seconds.. but the timing code is flawed. I noticed alot of effects that were probably meant to be slower.. the blinking score increment, the blinking eyes. The eyes blink so fast now it actually looks like the game is flickering.

It appears that alot of the stuff is updated based on the amount of frames, not the amount of time that has passed..

The instructions are very confusing. I understand the row/column number thing (I think). But, what causes the cascading removal of aliens? This is a dropping piece puzzle game. However, unlike Tetris, you aren’t battling time. Nothing is pushing you forward to make decisions rapidly
